If you are looking for a relaxing hike away from crowds but within an hour-long drive from Minneapolis or St. Paul, consider a trip to Wild River MN State Park along the banks of the St. Croix River.
Caribou Falls is an approximately 1-mile out-and-back hike, off of MN-61 between Tettegouche and Temperance State Parks. This is a subtly marked hike, meaning that although it is just a short distance away from the scenic highway that runs along Lake Superiors shore, you just might get to enjoy this waterfall by yourself. Enjoy the peacefulness of the Caribou River along your hike to the falls.
